Abstract

A study was carried out on the molecular characteristics of gene encoding for nucleocapsid protein(NP) of Newcastle disease virus (NDV) Bali-1/07. A portion of the fragment gene was amplified by reversetranscriptase-polymerase chain reaction (RT-PCR). The RT-PCR product purified from the gel was treatedwith Taq polymerase and cloned into plasmid pT7blueT vector. The recombinant plasmid was tranfectedinto Nova blue singles strain of Escherichia coli-competent cells and selected using white and blue colorselection method. Good white colonies were subcultured and tested for presence of expected gene fragmentby polymerase chain reaction (PCR). The correct size PCR product was recloned and sequenced. The PCRproduct of 540 base pairs were sequenced and aligned with several cognates genes of world NDVisolates.using Cluster IW. The phylogenetic analysis was then performed using MEGA 4. Phylogeneticanalysis showed that the NP gene of NDV Bali-1/07 is closely related with virulent NDVs such asGuangxii-11/03, KBNP-4152 and Ast2755/01 with nucleotide sequence homology of 92%, 91.4% and91%respectively, whereas the nucleotide sequence homology with avirulent NDVs such as LaSota and B1were 77%.

Abstract

Research to confirm the abnormalities of blood corpuscles in Bali ducks based on blood smear examination has been conducted. The research samples consisted of 105 ducks from various regencies in Bali. The blood smear examination was conducted by the method described in this literature and the data was collected and tabulated by means of the descriptive method. Erythrocyte abnormalities were: polychromasia (61.9%), anisocytosis (17.1%), poikilocytosis (21.0%). Abnormalities associated with leukocyte composition were: Lymphopenic (46.7%); Heterophylic (44.8%); Heteropenic (3.8%), also Thrombocyto penia (2.9%) was present in 105 ducks. In conclusion 61,9% ducks examined deal with regenerative anaemia. They also have some blood abnormalities such as basophylia, eosinophylia, heterophylia, heteropenia, lymphopenia, and monocytosis.
